Can't go to Line Number by double clicking Error.

Just wondering if anyone else has got this problem.. (and what setting i have to change to fix it)

Basically, after I had compiled a project, and recieved errors, I was able to go to that error by double clicking on it in the Status box down the bottom of the screen.

Now I can't do that, (the double clicking does nothing) and have to manually scroll through code (or use the Goto Line command, but I find scrolling quicker) to get to the Line number.

Any ideas?

Thanks.
